titleOfInvention PROCEDURE FOR THE PREPARATION OF SALMS AMMONIUM QUATERNARY POLYMERICAS.
abstract Process for the preparation of polymeric quaternary ammonium salts whose cationic units correspond to the formula **(Formula)** in which R1, R2, R3 and R4 are the same or different from each other and signify alkyl, cycloalkyl or alkenyl of 20 at most carbon atoms, optionally substituted, aryl or aralkyl; or else (R1 and R2) and/or (R3 and R4) together with the nitrogen atom to which they are attached form a heterocyclic ring with 3 to 6 members, optionally substituted.
